The Hodgdon magazine-style loading manual sold on newsstands is full of great info, loads on many chamberings including the new Induron powders. However, Hodgdon has left out load data for the 300 Savage, sad to say.
Some testing I did a couple of years ago:
Rem 700 Classic 300 Savage 24" factory barrel/chamber
WW brass
Sellier & Bellot 5.3 LR primer
Sierra 150 Pro hunter at 2.71" oal
IMR4166
38.9 grains --> 2462 fps
41.5 grains --> 2628 fps
42.6 grains --> 2695 fps (sub MOA)
For a '99 you'll need to seat them shorter at 2.6" or so.
In my 700 even the top load wasn't hot, with easy bolt lift and extraction. Of course that's not a '99, so start low and work up.
